What is the condenser terminal difference? What is the reason for the increase of terminal difference?
The end difference of condenser refers to the difference between the saturation temperature (exhaust temperature) under condenser pressure and the outlet temperature of condenser cooling water, which is called end difference.

The reasons for the increase in terminal differences are:

Scaling of condenser copper tube;

Air leakage at the steam side of condenser;

The cooling water pipe is blocked;

Cooling water reduction, etc.

Mathematical expression of terminal difference:

δt = tw2-tw 1ts = tw2+δt; ts = tw 1+δt+δt

As can be seen from the above formula, under the condition of constant t 1 and δt, reducing the end difference δ t of condenser is the main way to improve the vacuum of condenser. RCCS, the core technology product of Chongqing Huanji Low-carbon Energy-saving Technology Development Co., Ltd., can strengthen the heat exchange and online scale removal of condenser heat exchange tubes, and completely solve the problems of condenser scaling and poor heat exchange effect from the cold end.

capacitor

A heat exchanger that condenses the exhaust steam of steam turbine into water, also called reheater. Condensers are mainly used in steam turbine power plants and are divided into water-cooled condensers and air-cooled condensers.
